I need to upgrade ADFS 2016 to 2019. We use SQL db.
I installed a new ADFS 2019 server, added that into farm.
Both ADFS servers work fine.
I see this article: https://learn.microsoft.com/en-us/windows-server/identity/ad-fs/deployment/upgrading-to-ad-fs-in-windows-server
But that for WID db.
Using SQL Server to store the AD FS configuration database
The term "primary federation server" does not apply when the AD FS configuration database is stored in a SQL database instance because all federation servers can equally read and write to the AD FS configuration database that is using the same clustered SQL Server instance, as shown in the following illustration.
You can use SQL Server to configure two or more servers to work together as a server cluster to ensure that AD FS is made highly available to service incoming client requests. High availability provides a scale-out architecture in which you can increase server capacity by adding additional servers. Single points of failure are mitigated by automatic cluster failover.
What should be my next steps ?
Decomiss ADFS 2016
Install new server 2019
Add this server into ADFS farm
